    摘要： A process to manufacture nanocrystalline cellulose from cellulose having a low hemicellulose content, said process comprising the steps of:



    exposing said cellulose to a microemulsion composition for a first pre-determined period of time, thereby creating a soaked cellulose;
    optionally, exposing the soaked cellulose to a sonication step for a second predetermined period of time; and
    exposing the resulting mixture to a H2O2 with FeSO4 or CuSO4 under acidic conditions for a third pre-determined period causing hydrolysis of the cellulose;
    wherein the nanocrystalline cellulose will have a crystallinity index of more than 50% and an aspect ratio ranging from 10:1 length to width to 50:1 length to width.

    摘要： The present invention provides an automotive tire containing from 0.1 wt % to 50 wt % hydrophobic nanocellulose. Hydrophobic nanocellulose may include lignin-coated nanocellulose and/or a chemically modified surface to increase hydrophobicity. The nanocellulose may include cellulose nanofibrils and/or cellulose nanocrystals. The nanocellulose may be introduced into tire components such as inner liner, body ply, sidewall, beads, apex, belts, treads, cushion gum, and textile fabric. The nanocellulose may be obtained from a biomass-fractionation process utilizing an acid catalyst, a solvent for lignin, and water to generate a lignin-containing nanocellulose precursor, followed by mechanical treatment of the nanocellulose precursor to produce the nanocellulose. For example, the nanocellulose may be obtained from the AVAP® process. The tire may further include one or more additional components derived from lignocellulosic biomass. For example, the tire may contain lignin-derived carbon black, lignin-derived antioxidants, or biomass-derived silica. The tire may also contain synthetic polymers derived from biomass sugars.

    摘要： Porous cellulose microparticles and their use in, inter alias, cosmetic and pharmaceutic preparations are provided. These microparticles comprise cellulose I nanocrystals aggregated together, thus forming the microparticles, and arranged around cavities in the microparticles, thus defining pores in the microparticles. A method of for producing these microparticles is also provided. It involves mixing a suspension of cellulose I nanocrystals with an emulsion of a porogen to produce a mixture comprising a continuous liquid phase in which droplets of the porogen are dispersed and in which the nanocrystals of cellulose I are suspended; spray-drying the mixture to produce microparticles; and if the porogen has not sufficiently evaporated during spray-drying to form pores in the microparticles, evaporating the porogen or leaching the porogen out of the microparticles to form pores in the microparticles.
